Linear (spectro) polarimetry is usually performed using separate photon flux measurements after spatial or temporal polarization modulation. Such classical polarimeters are limited in sensitivity and accuracy by systematic effects and noise. We describe a spectral modulation principle that is based on encoding the full linear polarization properties of light in its spectrum. Such spectral modulation is obtained with an optical train of an achromatic quarter-wave retarder, an athermal multiple…

Spectral line polarimetry with a channeled polarimeter.

This work shows how a dual-beam implementation also enables spectral line polarimetry at the intrinsic resolution, as in a classic beam-splitting polarimeter, and performs an error analysis to compare the accuracy of spectral lineolarimetry to continuum Polarimetry, degraded by a residual dark signal and differential transmission.

Five-dimensional optical instrumentation: combining polarimetry with time-resolved integral-field spectroscopy

We present implementations of optical instrumentation that records five dimensions of light: polarization state as a function of wavelength, two spatial dimensions, and time. We focus on the optimal

Spectroscopic Mueller matrix polarimeter based on spectro-temporal modulation.

The spectral polarization modulation provided by the polarization state generator can produce five separate channels in the Fourier domain, which leads to a larger bandwidth of each channel than that of the existing spectral modulated spectroscopic Mueller matrix polarimeters.

Spectroscopic polarimetry with a channeled spectrum.

A pair of thick birefringent retarders is incorporated into the spectroscopic polarimeter, so the generated channeled spectrum is composed of three quasi-cosinusoidal components carrying the information about the SOP of the light that is being measured.
